Dell e4300 blue light charge indicator blinking

[Row1]

Hi, everyone - I have a dell e4300 - actually I have three. On one, when it is plugged in to charge, the blue light that indicates that it is plugged in and charging, which normally would be blue continuously, is blinking, or oscillatiing, off and on.

I bent the pin on the inside of the cord slightly in order to maybe get a better contact, and bent the barrel slightly for same reason - the blinking is the same.

So, it does not quite seem like this is a weak, variable connection. Also, I get the same thing with another charger cable. Does this mean something?

Well ,the more I look at this, the less regular it seems, but it does come on momentarily every several seconds. It sure is not charged up, despite being plugged in for over 24 hours.

How old is your battery?

Pretty old; I could swap batteries with another e4300 and see if that makes a diff.

Yes do that. My suspicion is that the battery is so old that it needs to be replaced.
